My invention relates to shaking conveyers and has particularly l,reference to the connecting members of the:conveyer trough, and in particular to an vinterconnection of the type in which the connecting attachments abut against one another by cylindrical contactysurfaces under the action of alocking or tightening member, so

that the conveyer sections-are capable of taking' A transversely to the working direction of the connection of shaking conveyers the connectingv trough and `consequently this bolt is subjected to very high bending stresses. In another known means is formed by a transverse bar xed to the underside of each element ythe both ends of which bar laterally project beyond the conveyer sections, one-of these bars carrying on either end a pivoted Ll-shaped yoke adapted 'to be swung over the respective end of the bar of the adjacent section, the two co-opcrating transverse bars being locked in position by wedge mounted on said yokeand adapted-to be fixed between the two bars. Curved contact surfaces on the wedge and the ends of the barsv enable a certain angular mutual displacement of the conveyer elements in avertical plane. In this construction no direct transmission of power takes place between the two bar ends, but the forces passing from the one bar to the companion bar are transmitted through the wedge, whereby in conlnection with the possibility of the angular displacement of the sections an angularly broken transmission of the forces is caused from one bar tc the other. Furthermore, such transverse connecting bars can be used only for conveyer section of one sole determined width. `Finally the arrangement of the connecting-transverse bars on the underside ofV the conveyer elements as also the first described construction suffer present invention the connecting attachments' are provided on the side wall of the sections and protrude beyond them in transver direction. The attachments are formed with cylindrical contact surfaces which extend horizontally and transversely of the working direction of the conveyer and are immediately pressed against one another by a tightening member disposed in parn allel with the working direction of the conveyer,

(Cl. Hi8- 220) In this new construction the connecting attachments can be situated at such a level on the side wall of the conveyer sections, that the passage of the power from one-section to the other takes placev at or approximately at the level of the center of gravity of the cross section of the troughs without a power moment `being exerted upon the sheet metal plates of the sections.- Furthermore, a iin-like shape canA be given to the attachments, so that, likewise in ,contrast to the known constructions, a preserving gradual transition of the conveyer forces from the attachments to the sheet metal plates of the sections is obtained. a,

If the running wheels of the conveyer are mounted on the attachments in a. manner known as such, the arrangement of the latter on the side walls of the sections aiords a further advantage in so far asA the conveyer then hasV a. very small structural height, when compared with the constructions in which the running wheels are combined with connecting attachments arranged on the underside of the conveyer sections.

Furthermore the fact, that the two co-operating connecting attachments directly abut against one another by their cylindrical contact surfaces. results in a more favorable transmission of the power from one connecting element to the companion element, in comparison with the abovementioned known construction', and further, likewise in contrast to the said known construction,

the conveyer forces can be transmitted immediy ately, that means. without being spaced from the wall of the elements, directly along this wall.

The tightening member serving to interconneet the co-operating attachments may be of any suitable construction, as described hereinafter in detail.

In order that my invention may be clearly understood and readily carried into effect, some embodiments of the same are illustrated in the accompanying drawings by way of example, the drawings representing various examples both of the construction of the connecting attachments and oi the tightening member; In these drawembodiment, in side fourth embodimentI in side elevation andsec tional top view. l

My improved connection of conveyer sections substantially consists of two attachments a and b, preferably welded to the outside of the side walls of the conveyer section r and extending transversely of this wall, these attachments under the action of a tightening member abutting against one another by means of cylindrical. sur-` faces c and d which extend horizontally and transversely of the working direction of the conveyer. As clearly to be seen in the drawings, the attachments may have a fin-like shape, that means, they may have a cross section decreasing in width or height or both in width' and height from their confronting ends', so as to have a correspondingly tapering rear end, and, consequently, they transmit to the plates of the conveyer sections forces which decrease according to these decreasing cross sections. The transmission of the forces to the sections thus takes place without sudden transition, and in a preserving gradual manner.

The attachments a and b are connected to one another by a tighteningmember arranged when in operative position in parallel with the working direction of the conveyer and hingedly mounted on the attachments a which for this purpose are bifurcated. In the embodiments according to Figures 1 to '7 the tightening member is formed by a screw bolt e hinged to theA attachment a, so as to be swung in a vertical plane, and adapted to engage an eye f of an inversec U-shaped cross section provided on the attachment b. In order to secure the nuts y in tightening position, the eye f is provided with a small nose h, see Figures 1, 2, 5, and 7, by which the bolt e and the nuts g are protected from being swung downward.

As shown in Figures 1 to e, the bolt e may be arranged for swing motion in a vertical plane only or both in vertical and horizontal planes or it may be arranged for ball. joint motion, as shown in Figure 5. In this latter case the eye f is inclined on its outside in such a manner, that when the tightening bolt has been swung into the position shown in Figure 5, the conveyer section which carries the attachment b can be lifted from the other element.'

As illustrated in Figures 6 and 7, the bolt e can also be articulated in itself for example at z' as shown.

In the embodiment shown in Figures 8 and 9 the tightening member is formed by a U-shaped yoke 7c pivotally mounted on the attachment a for vertical and horizontal swing motion. The yoke Ic has mounted on it a screw wedge m abutting against an extension b of the attachment b, and whenwedge m is tightened, it presses the cylindrical surface d of the attachment b against the cylindrical counterface c of the attachment a.

In the embodiment illustrated.A in Figures 5 to 9 in which the tightening member is mounted for swing motioninna horizontal and vertical plane or is provided with a ball joint,lthe advantage is obtained that each two adjacent conveyer sec` tions are capable of positioning themselves angularly to one another in a vertical plane within certain limits, so that the conveyer can be adapted toa corresponding extent to the unevennesses of the'oor.

In all my new constructions of shaking conveyer connections the pivot axis n of the tightening member e or 7c may simultaneously form a journal for the running wheels o of the conveyer, as illustrated in Figures 1, 3, and 5 by Way of example. Furthermore, 4in all these constructions that part of theattachment a or b which carries the tightening member can be disposed at such a level on the side wall of the conveyer sec.

ua moment of force on the conveyer trough. Since the tightening members e or 1c are arranged in parallel with the longitudinal direction of the conveyer, they are stressed by the forces to be transmitted by them in a very favorable manner,

that means, they are subjected to traction only.

Finally, the co-operating contact surfaces c and d of the connecting attachments are situated close to the side wall of the conveyer trough, which is likewise favorable for the transmission of the forces. v v
